Illaoi seems really... oppressive
Now I have no idea how oppressive she's supposed to be, but after facing her a few times, i think her numbers should be tweaked a bit. I'm mainly thinking on her tentacles, they do a bunch of damage, it's like getting punched by her herself, but without her being there. I don't know, maybe I'm just stupid or my champions aren't tanky enough (i know Shaco wasn't, but I'm not surprised about that).
